<p><a class="link" href="glib-Automatic-String-Completion.html#GCompletion" title="struct GCompletion"><span class="type">GCompletion</span></a> provides support for automatic completion of a string
using any group of target strings. It is typically used for file
name completion as is common in many UNIX shells.</p>
<p>A <a class="link" href="glib-Automatic-String-Completion.html#GCompletion" title="struct GCompletion"><span class="type">GCompletion</span></a> is created using <a class="link" href="glib-Automatic-String-Completion.html#g-completion-new" title="g_completion_new ()"><code class="function">g_completion_new()</code></a>. Target items are
added and removed with <a class="link" href="glib-Automatic-String-Completion.html#g-completion-add-items" title="g_completion_add_items ()"><code class="function">g_completion_add_items()</code></a>,
<a class="link" href="glib-Automatic-String-Completion.html#g-completion-remove-items" title="g_completion_remove_items ()"><code class="function">g_completion_remove_items()</code></a> and <a class="link" href="glib-Automatic-String-Completion.html#g-completion-clear-items" title="g_completion_clear_items ()"><code class="function">g_completion_clear_items()</code></a>. A
completion attempt is requested with <a class="link" href="glib-Automatic-String-Completion.html#g-completion-complete" title="g_completion_complete ()"><code class="function">g_completion_complete()</code></a> or
<a class="link" href="glib-Automatic-String-Completion.html#g-completion-complete-utf8" title="g_completion_complete_utf8 ()"><code class="function">g_completion_complete_utf8()</code></a>. When no longer needed, the
<a class="link" href="glib-Automatic-String-Completion.html#GCompletion" title="struct GCompletion"><span class="type">GCompletion</span></a> is freed with <a class="link" href="glib-Automatic-String-Completion.html#g-completion-free" title="g_completion_free ()"><code class="function">g_completion_free()</code></a>.</p>
<p>Items in the completion can be simple strings (e.g. filenames), or
pointers to arbitrary data structures. If data structures are used
you must provide a <a class="link" href="glib-Automatic-String-Completion.html#GCompletionFunc" title="GCompletionFunc ()"><span class="type">GCompletionFunc</span></a> in <a class="link" href="glib-Automatic-String-Completion.html#g-completion-new" title="g_completion_new ()"><code class="function">g_completion_new()</code></a>, which
retrieves the item's string from the data structure. You can change
the way in which strings are compared by setting a different
<a class="link" href="glib-Automatic-String-Completion.html#GCompletionStrncmpFunc" title="GCompletionStrncmpFunc ()"><span class="type">GCompletionStrncmpFunc</span></a> in <a class="link" href="glib-Automatic-String-Completion.html#g-completion-set-compare" title="g_completion_set_compare ()"><code class="function">g_completion_set_compare()</code></a>.</p>
<p>GCompletion has been marked as deprecated, since this API is rarely
used and not very actively maintained.</p>
